Description
These lenses are varifocal lenses designed for 1/3-inch megapixel cameras with 3 megapixels (MPx) or less in resolution. These lenses, which were
designed for CS-mount cameras, produce high precision images from the image center to the image corner, fully exploiting the performance of megapixel
cameras. Megapixel lenses are best suited for high-quality image surveillance with a megapixel camera as well as with a standard definition camera.

FLANGE FOCAL ADJUSTMENT
Megapixel lenses work with Pelco's Sarix™ cameras. The auto back focus feature of Sarix cameras saves time because a single button sets the auto back
focus mechanism. To set the auto back focus:
1. Press the button once to center the auto back focus mechanism and to fully open the iris.
2. Press and hold the button for three seconds to start the auto back focus mechanism.
If you do not have a camera with auto back focus and you cannot get the lens to focus despite repeated attempts, perform the following steps to adjust the
specific camera’s flange focal length (refer to the appropriate camera manual for detailed instructions).
1. Open the lens iris.
2. Set the zoom at the wide end and the focus at the near end for 13M2.2-6, 13M2.8-8, and 13M2.8-12. For the 13M15-50 lens, set the zoom at the
telephoto end and the focus at the infinity end.
3. Operate the flange focal length adjustment mechanism on the camera, and then focus on an object at 11.8 inches (0.3 m) from the lens for the
13M2.2-6, 13M2.8-8 and 13M2.8-12 lenses. For the 13M15-50 lens, focus on an object that is more than 8.8 yards (8 m) from the lens.
4. Confirm the focus at the telephoto end, around the middle, and at the wide end throughout the zoom range. (If you cannot set the focus despite the
above procedure, try again.)
